At the beginning of the year we had many lessons on what each center should look like at the end of each day. I have pictures up to show the kids, and I have two "Clean Up Commanders." I have tried many strategies to entice my class to clean up after themselves. I try to make clean up time into a game and I award stickers, blocks in the jar (class reward system), table points, skittles, etc. It seems like there are a few kids who do care and end up cleaning for everyone, while the others are being lazy. Nothing is working to get these kids to clean up after themselves. Many seem very lazy. Some students will drop a crayon on the floor and leave it there. Then others will walk by it or step on it like they don't even care. One of the worst areas of the room is the computer area. The computers run all day long, so I can't always be available to monitor the cleanliness of the computer area. The students have to write things down when they are on the computer. I have told them repeatedly to put the papers in their mailboxes. Halfway through the day I find a ton of papers all around the center. I'm to the point where I want to take centers away. I don't think these kids respect the property in the room. I need some ideas.
